Scientists have successfully created the world’s smallest magnet – it’s a single atom, and it could be an integral part of computers in the future.
The one-atom magnet was made by a team of researchers from the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland, and it’s believed to be the most stable version ever created.
Magnetic storage devices like hard drives and SD cards are a part of everyday life – but as computers get smaller, so too must their storage systems.
It’s difficult to find something smaller than an atom, so creating these rare magnets is seen as a vital step towards the creation of microscopic, futuristic computers.
The team’s discovery is notable because magnets this small are hard to keep magnetised, meaning they wouldn’t be able to hold anything for very long if they were used in data storage devices. .. see more
